The 1N914 is a small signal diode similar to the 1N4148 and is common in many older electronics. The 1N914 is general purpose and can be used in a multitude of different applications.

5W zener diodes that are great for use in tube amps. These are commonly used to drop B+ voltages for tube modification compatibility or to create low power modes for the amp. A zener is a semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.

The 2N5135 is a silicon NPN transistor in a TO-105 case. This transistor is a close match to the rare 2N5133 but with higher voltage ratings and is in a larger package. The hFE range is less wide than the 2N5133 with more values in the range found in the batches used on vintage Big Muff pedals. The lower hFE range also makes these a great option for silicon fuzz pedals.
